Inclination and Intrusion
Sensors Disable Switch
It is recommended that the
inclination and intrusion
sensors be deactivated if pets
are left in the vehicle or if the
vehicle is being transported.
With the vehicle turned off,
press
oin the overhead
console. The indicator light will
come on momentarily,
indicating that the sensor has
been disabled until the next
time the alarm system is
armed.
Steering Column Lock
If equipped, the steering
column lock is a
theft-deterrent device. This
feature locks the steering
column when the vehicle is
turned off and the driver door
is opened, or when the driver
door is opened and then the
vehicle is turned off. The
steering column unlocks when
the vehicle is turned on. The Driver Information Center
(DIC) may display one of these
messages:
.A message to service the
steering column lock
indicates that an issue has
been detected with the
column lock feature and the
vehicle should be serviced.
.A message that the steering
column is locked indicates
that the engine is running,
but the steering column is
still locked. It is normal for
the column to be locked
during a remote start, but
the column should unlock
after the brake pedal is
pressed and the vehicle is
started. No message will
display during a remote
start.
.A message that the steering
wheel must be turned and
the vehicle must be started
again indicates that the
column lock mechanism is
bound, the column locking
device was unable to unlock
the steering column, and thevehicle did not start. If this
happens, immediately turn
the steering wheel from side
to side to unbind the column
lock. If this does not unlock
the steering column, turn the
vehicle off and open the
driver door to reset the
system. Then turn the
vehicle on and immediately
turn the steering wheel side
to side for about 15 seconds.
In some cases, it may take
significant force to unbind
the column.
To keep the steering column
from binding, straighten the
front wheels before turning
off the vehicle.
Immobilizer
See Radio Frequency
Statement 0477.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.

78 Seats and Restraints
windshield breakage may also
occur from the front outboard
passenger airbag.
.Airbags are designed to
inflate only once. After an
airbag inflates, you will need
some new parts for the
airbag system. If you do not
get them, the airbag system
will not be there to help
protect you in another crash.
A new system will include
airbag modules and possibly
other parts. The service
manual for the vehicle
covers the need to replace
other parts.
.The vehicle has a crash
sensing and diagnostic
module which records
information after a crash.
See Vehicle Data Recording
and Privacy0479 and
Event Data Recorders 0480.
.Let only qualified technicians
work on the airbag system.
Improper service can mean
that an airbag system will
not work properly. See your
dealer for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position.
The passenger airbag status
indicator will light on the
overhead console when the
vehicle is started.
The words ON and OFF, and
the symbols for on and off, will
be visible during the system
check. When the system check
is complete, either the word
ON or OFF, and the symbol for
on or off, will be visible. See
Passenger Airbag Status
Indicator 0133. The passenger sensing
system turns off the front
outboard passenger frontal
airbag under certain
conditions. No other airbag is
affected by the passenger
sensing system.
The passenger sensing
system works with sensors
that are part of the front
outboard passenger seat and
seat belt. The sensors are
designed to detect the
presence of a properly seated
occupant and determine if the
front outboard passenger
frontal airbag should be
allowed to inflate or not.
According to accident
statistics, children are safer
when properly secured in a
rear seat in the correct child
restraint for their weight
and size.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -

80 Seats and Restraints
When the passenger sensing
system has allowed the airbag
to be enabled, the ON
indicator will light and stay lit
as a reminder that the airbag
is active.
For some children, including
children in child restraints, and
for very small adults, the
passenger sensing system
may or may not turn off the
front outboard passenger
frontal airbag, depending upon
the person's seating posture
and body build. Everyone in
the vehicle who has outgrown
child restraints should wear a
seat belt properly—whether
or not there is an airbag for
that person.
{Warning
If the airbag readiness light
ever comes on and stays on,
it means that something may
be wrong with the airbag
system. To help avoid injury
to yourself or others, have
(Continued)
Warning (Continued)
the vehicle serviced right
away. See Airbag Readiness
Light0132 for more
information, including
important safety
information.
If the On Indicator Is Lit
for a Child Restraint
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag if the system
determines that an infant is
present in a child restraint. If a
child restraint has been
installed and the ON indicator
is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such
as blankets, cushions, seat
covers, seat heaters,
or seat massagers. 4. Reinstall the child restraint
following the directions
provided by the child
restraint manufacturer and
refer to Securing Child
Restraints (With the Seat
Belt in the Rear Seat) 0102
or Securing Child
Restraints (With the Seat
Belt in the Front Seat)
0 104.
Make sure the seat belt
retractor is locked by
pulling the shoulder belt all
the way out of the
retractor when installing
the child restraint, even if
the child restraint is
equipped with a seat belt
lock off. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor.
5. If, after reinstalling the child restraint and
restarting the vehicle, the
ON indicator is still lit, turn
the vehicle off. Then
slightly recline the vehicle

6. Restart the vehicle andhave the person remain in
this position for two to
three minutes after the ON
indicator is lit.
{Warning
If the front outboard
passenger airbag is turned
off for an adult-sized
occupant, the airbag will not
be able to inflate and help
protect that person in a
crash, resulting in an
increased risk of serious
injury or even death. An
adult-sized occupant should
not ride in the front
outboard passenger seat,
if the passenger airbag OFF
indicator is lit.
Additional Factors
Affecting System
Operation
Seat belts help keep the
passenger in position on the
seat during vehicle maneuvers and braking, which helps the
passenger sensing system
maintain the passenger airbag
status. See
“Seat Belts” and
“Child Restraints” in the Index
for additional information
about the importance of
proper restraint use.
A thick layer of additional
material, such as a blanket or
cushion, or aftermarket
equipment such as seat
covers, seat heaters, and seat
massagers can affect how well
the passenger sensing system
operates. We recommend that
you not use seat covers or
other aftermarket equipment
except when approved by GM
for your specific vehicle. See
Adding Equipment to the
Airbag-Equipped Vehicle 083
for more information about
modifications that can affect
how the system operates.
The ON indicator may be lit if
an object, such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device, is put on an unoccupied seat.
If this is not desired, remove
the object from the seat.
{Warning
Stowing articles under the
passenger seat or between
the passenger seat cushion
and seatback may interfere
with the proper operation of
the passenger sensing
system.
Servicing the
Airbag-Equipped
Vehicle
Airbags affect how the vehicle
should be serviced. There are
parts of the airbag system in
several places around the
vehicle. Your dealer and the
service manual have
information about servicing
the vehicle and the airbag
system. To purchase a service
manual, see Publication
Ordering Information
0476.

Warning lights and gauges can
signal that something is wrong
before it becomes serious
enough to cause an expensive
repair or replacement. Paying
attention to the warning lights
and gauges could prevent
injury.
Some warning lights come on
briefly when the engine is
started to indicate they are
working. When one of the
warning lights comes on and
stays on while driving, or when
one of the gauges shows
there may be a problem, check
the section that explains what
to do. Waiting to do repairs
can be costly and even
dangerous.

The airbag readiness light
comes on for several seconds
when the vehicle is started.
If the light does not come on
then, have it fixed immediately.
{Warning
If the airbag readiness light
stays on after the vehicle is
started or comes on while
driving, it means the airbag
system might not be working
properly. The airbags in the
vehicle might not inflate in a
crash, or they could even
inflate without a crash. To
help avoid injury, have the
vehicle serviced right away.
If there is a problem with the
airbag system, a Driver
Information Center (DIC)
message may also come on.
Passenger Airbag
Status Indicator
The vehicle has a passenger
sensing system. See
Passenger Sensing System
0 78. The overhead console
has a passenger airbag status
indicator.
When the vehicle is started,
the passenger airbag status
indicator will light ON and OFF,
and the symbols for on and
off, for several seconds as a
system check. Then, after
several more seconds, the
status indicator will light either
ON or OFF, and the symbol for
on or off, to let you know the
status of the front outboard
passenger frontal airbag. If the word ON, and the
symbol for on, are lit on the
passenger airbag status
indicator, it means that the
front outboard passenger
frontal airbag is allowed to
inflate.
If the word OFF, and the
symbol for off, are lit on the
passenger airbag status
indicator, it means that the
passenger sensing system has
turned off the front outboard
passenger frontal airbag.
If, after several seconds, both
status indicator lights remain
on, or if there are no lights at
all, there may be a problem
with the lights or the
passenger sensing system.
See your dealer for service.
